The 700 as stated was a little slow but a lot of the performance issues and screen issues they fixed in the 900 imho
As the system runs with not a industry standard processor with regards to power, anyone who try's to run Windows on them is going to be disappointed and find it lacking greatly.
Its like trying to run WindowsXP on a mobile phone or PDA, the limitations of the architecture just makes it stupid thing to do.

forget the 700 and get the 900 with Linux and its perfectly usable for what it is intended to do and be.
